DST Computer Services is a Swiss company founded in 1973 by Mr. Kent Gordis, a brilliant mathematician and a pioneer in the field of data processing. Mr Gordis was the original author of the pipe stress analysis program PIPESTRESS which he continuously developed over a 40 year period: at first, in collaboration with Ebasco Services Inc., architect engineer on several nuclear power plants in the USA, Japan and Taiwan and later with large engineering companies. He presented and published several mathematical papers.
Over the years, DST has employed highly qualified engineers and programmers who have worked with Mr. Gordis to assure the continued development of PIPESTRESS and associated programs.
DST has licensed PIPESTRESS which is now integrated with its graphical pre- and post- processor, Editpipe, to over 400 companies in 30 different countries and is used for maintenance piping calculations and in the design of third and fourth generation reactors.
Performs all calculations required by the nuclear (and non nuclear) piping codes in a single program execution
Has been continuously maintained for more than 40 years
Has been used by more than 400 engineering organizations in 30 countries to analyze piping in more than 50 nuclear power plants
Is being used as the main piping analysis software for calculations in the new reactors: EPR, AP1000 and AC-1000. Many of the piping calculations for Westinghouse AP600 plant were performed using PIPESTRESS and these calculations were accepted by the US NRC when they issued a standard plant license for the AP600
Approved by the US NRC for AP1000 piping calculations
